About our sand mastic in Brèibhig
Sand mastic skins over fairly quickly, but it takes longer to harden fully. Traditional guidance is not to paint over it and we will advise if you’re redecorating. We work on stone surrounds, timber door frames and sash and case windows, and people most often call us about mastic round period door frames that has failed and a silicone bead on a sash window that spoils the look.
Outdoor sealant needs a dry surface, so window work around Brèibhig is planned around the weather, and longer journeys are planned in advance. Let us know about access to every frame, including any upstairs.
All our work is covered by a one-year guarantee.

Why deal with it now?
Filling over old, loose mastic doesn’t last. Raking out and preparing the joint gives it a sound base so the new work lasts. In an older home around Brèibhig, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.

- The joint is raked out and cleaned.

FAQs for Brèibhig
Does living near the coast affect sand mastic in Brèibhig?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. Walls facing the sea are generally the first to need attention.
Will you come out to Brèibhig?
Yes, Brèibhig is covered. Our work covers the whole of Scotland, islands included, and smaller places are part of that. Longer journeys are simply planned in advance.
Should I try DIY first?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
Can you work on commercial sites?
Yes. We’ve worked for hotels, offices and other businesses.
How long does sand mastic take to harden?
A skin forms quite soon, but full hardening takes longer. We will explain what to expect before we leave.
Do you guarantee sand mastic work?
Our 12-month guarantee applies to all our work.
Where is Mr Mastic based?
We are a Crawley-based firm. We work across South East England, London and Scotland.
Do the sealants smell?
Possibly a little. Any smell clears as the sealant cures.
Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Keep sills and gutters clear so water drains away
- Go gently near the mastic when preparing windows
- Leave the new mastic unpainted
- Get any rot dealt with first
Avoid painting over the new mastic, as traditional guidance advises. Ask us before any decorating around it.
It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.
Different surfaces, different methods
Timber door frames

Windows and doors in Brèibhig
Brèibhig is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
If you look after a building such as Castlebay Community School, larger buildings have plenty of frames, and the mastic around each one ages.
